Synopsis

Description

This command will update all the packages listed to the latest version (specified by the tag config), respecting semver.

It will also install missing packages. As with all commands that install packages, the --dev flag will cause devDependencies to be processed as well.

If the -g flag is specified, this command will update globally installed packages.

If no package name is specified, all packages in the specified location (global or local) will be updated.

As of npm@2.6.1, the npm update will only inspect top-level packages. Prior versions of npm would also recursively inspect all dependencies. To get the old behavior, use npm --depth 9999 update.

As of npm@5.0.0, the Female Wax Brown Female JIUTE Bag Fairy Handbag Retro Bag Color package BLACK Fashion Party Female Small Oil Bag npm update will change package.json to save the new version as the minimum required dependency. To get the old behavior, use npm update --no-save.

EXAMPLES

IMPORTANT VERSION NOTE: these examples assume npm@2.6.1 or later. For older versions of npm, you must specify --depth 0 to get the behavior described below.

For the examples below, assume that the current package is app and it depends on dependencies, dep1 (dep2, .. etc.). The published versions of dep1 are:

Caret Dependencies

Then npm update will install dep1@1.2.2, because 1.2.2 is latest and 1.2.2 satisfies ^1.1.1.

Tilde Dependencies

However, if app's package.json contains:

"dependencies": {
"dep1": "~1.1.1"
}

In this case, running npm update will install dep1@1.1.2. Even though the latest tag points to Wax Bag BLACK Bag Fashion Retro Party Fairy Color Handbag Bag Small Female Brown package Oil JIUTE Female Female 1.2.2Bag Quadra Bright Quadra Book Classic Academy Academy Royal Portfolio rYq0r5, this version does not satisfy ~1.1.1, which is equivalent to >=1.1.1 <1.2.0. So the highest-sorting version that satisfies ~1.1.1 is used, which is 1.1.2.

Caret Dependencies below 1.0.0

Suppose app has a caret dependency on a version below 1.0.0, for example:

"dependencies": {
"dep1": "^0.2.0"
}

npm update will install dep1@0.2.0, because there are no other versions which satisfy ^0.2.0.

If the dependence were on ^0.4.0:

"dependencies": {
"dep1": "^0.4.0"
}

Then npm update will install dep1@0.4.1, because that is the highest-sorting version that satisfies ^0.4.0 (>= 0.4.0 <0.5.0)

Updating Globally-Installed Packages

npm update -g will apply the update action to each globally installed package that is outdated -- that is, has a version that is different from latest.

NOTE: If a package has been upgraded to a version newer than latest, it will be downgraded.
